摘要: 随着智慧矿山的快速发展,实时精准识别爆堆矿石铲装过程中的大块矿石已成为保障运输安全与效率的关键需求。针对露天矿爆堆矿石图像存在形状高度不规则、颗粒间严重重叠、图像分辨率低及特征稀疏等挑战,文中提出一种轻量化爆堆矿石图像分割算法,通过多维度模型优化实现精度与效率的平衡。首先,使用DynamicHGNetv22(Dynamic High Performance GPU Network version2)层级图网络的拓扑特性重构主干网络,通过动态路由机制压缩冗余特征,将模型体积缩减42.4%;其次,设计HSFPN(High-level Screening-feature Fusion Pyramid)高阶筛选特征融合金字塔作为颈部网络,采用通道注意力引导的多尺度特征筛选机制,在降低27.4%计算量的同时提升跨尺度特征融合能力;然后,构建轻量化分割头(Light Head),通过深度可分离卷积与特征蒸馏技术进一步优化计算效率;最后,引入EMASlideLoss(Exponential Moving Average SlideLoss)损失函数,基于指数移动平均策略动态调节难易样本权重,显著提升模型对低质量矿石目标的边缘分割精度。实验结果表明,相较于 YOLO11n-seg基准模型,所提方法的参数量和计算量分别缩减42.4%和27.4%,mAP50和mAP50:95分别提高了0.1%和2.1%,不仅满足矿山场景高精度实时分割需求,其轻量化特性更是可直接部署于边缘计算设备,为智能铲装系统的大块矿石预警提供可靠技术支撑。

Abstract: With the rapid development of smart mines,the real-time and precise identification of large rocks in the blasting operation for ore loading has become a key requirement for ensuring transportation safety and efficiency.To address the challenges posed by highly irregular shapes,significant overlap among particles,low image resolution,and sparse features in the images of the blasted heap ore,this paper proposes a lightweight image segmentation algorithm for blasted heap ore that achieves a balance between accuracy and efficiency through multi-dimensional model optimization.Firstly,the topological characteristics of the DynamicHGNetv2(Dynamic High Performance GPU Network version2) hierarchical graph network are utilized to reconstruct the backbone network,compressing redundant features through a dynamic routing mechanism,which reduces the model size by 42.4%.Secondly,the HSFPN(High-level Screening-feature Fusion Pyramid) is designed as the neck network,employing a multi-scale feature screening mechanism guided by channel attention,which reduces the computational load by 27.4% while enhancing the ability for cross-scale feature fusion.Subsequently,a lightweight segmentation head is constructed,optimizing computational efficiency further through depthwise separable convolutions and feature distillation techniques.Finally,the EMASlideLoss(Exponential Moving Average SlideLoss) loss function is introduced,dynamically adjusting the weights of difficult samples based on an exponential moving average strategy,significantly improving the model's edge segmentation accuracy for low-quality ore targets.Experimental results indicate that,compared to the YOLO11n-seg benchmark model,the proposed method reduces the number of parameters and computational costs by 42.4% and 27.4%,respectively,while mAP50 and mAP50:95 improve by 0.1% and 2.1%,respectively.This not only meets the needs for high-precision real-time segmentation in mining scenarios but also can be directly deployed on edge computing devices,providing reliable technical support for early warning systems for large ore in smart shoveling systems.
